| Abstract: | The luminescent properties of Eu ion incorporated in a Y-type zeolite have been studied. The emission spectrum at room temperature is due to the transition between 5D and 7F levels of the Eu3+ ion. However the emission band for Eu3+ decreased as this compound was degassed at above 300°C and the band emission, peaked at 445 nm, appeared. This band emission is associated with Eu2+ 5d to 4f transition. |
